2000 150hp ficht ram injection oil leak

[coreythompson_85]

Hi all, have a 2000 150hp ram injection and a couple questions. Starboard side throttle body intakes have some oil coming out of them, normal? And seem to have an oil leak coming from bottom of oil intake manifold or pressure switch, common problem? Any info would be great thanks.

Re: 2000 150hp ficht ram injection oil leak

Your oil-manifold/pressure switch should not leak oil, get it corrected.
As for the throttle body, a bit different.
It might be due to blow-back and leaf valves not sealing properly. It might be due to stb and port side throttle shafts are not properly synchronized.
The fichts have always had more or less blow-back and oil in the silencer box. Partly it may be related to engine load and propeller selection. The more the TPS is 'open' and the lower the rev of the engine the worse it gets.

thanks a lot, should i be worried about the blowback then or just attribute it to being a ficht

All engines have some blow-back, but as the ficht has the oil-injection n the valve body throat it may look a bit worse than others. Fix the manifold leak, check the synch of the throttle plates and keep on.

By synch you just mean the linkage going from port to starboard between the throttle body openings right. I just want to ensure that the angle is the same on both sides correct? Looking at it yesterday the adjustment of either side seemed identical yet the blowback was only coming from the starboard side.

The throttle body alignment is correct. Was trying to diagnose on muffs the other day got no oil alarm when idling. I am waiting for new oil lift pump with pressure switch which I have ordered. Am curious as to whether bad lift pump may be causing the excess oil to build up only on the starboard side throttle body intakes. When I change out the lift pump I will be switching to xd-50 oil as I believe the guy I just bought it from was running **** oil through it. Was wondering if anyone could tell me if the E150FSLSSM gets a no oil alarm from anywhere other than the pressure switch on the front of the lift pump. I have ordered the software and cable as well but am curious in the meantime.

The switch is what gives the No-Oil alarm, but there are other alarms related to the oil-injector.
When you get the software and cable, run a static oil injector test and monitor that you get almost the same amount of oil in all venturie throats.

Re: 2000 150hp ficht ram injection oil leak

Thanks for the quick reply will try as soon as i get the software, so youre saying the actual no oil alarm can only come from the pressure switch but may be caused due to a problem in the lines from the oil injector? All 6 lines coming off injection manifold appear primed with no air bubbles. Are u thinking that oil could be leaking out of several lines in the injector even when a pulse is not occuring causing the pressure to drop at the lift pump where the sensor is. If so is the oil injector serviceable or will i need to order a new one?

Re: 2000 150hp ficht ram injection oil leak

Not quite. The system takes for granted that the same amount of oil goes to every intake at each oil solenoid activation. However a blockage, uneven length of oil lines etc might lead to uneven distribution. If engine has been run with crappy oil quality, clean the tank and keep the return hose to oil tank off until everything has been flushed with clean oil. Do not forget to empty and clean the tank and filter before filling new oil.

wow, i could believe this is written about my engine... exactly the same- a 2000 150hp ficht ram, and i also noticed some oil only in the stbd intakes- the port side is dry. i had one time the no oil alarm.

i noticed a slight leak on the oil supply line and fixed it. also checked , cleaned and sprayed all sensors regarding oil supply and also the oil tank. currently since lets say 10-15 operating hours the problem is gone as sudden as it has come, currently the beast runs without any issues. did not change any sensor or the oil pump- oil comes plenty out of the return line, the manifold is filled also without any air bubbles, but had not a leak there. the engine seems to be sensitive to any oil leaks .

it sound strange that there seems to be a tendency for oil in the stbd manifold at this engine and nobody knows why.

Re: 2000 150hp ficht ram injection oil leak

Still waiting for service manual is it ok to take the return line off while the engine is running to check flow. How often should there be a pulse from the oil injector at idle?

Re: 2000 150hp ficht ram injection oil leak

yes its ok with the return line- but keep it in the vicinity of the tank because even at idle there will be a lot of oil splashing out of the line when the pump is working. i by myself was surprized how much it is.

when the engine idles and you take your hands at the line from the pump to the injector distributor you shoul feel frequent pulses at the line.- definitly several pulses at one second.

what is your exact problem with the engine ? do you have a no oil light ?

Re: 2000 150hp ficht ram injection oil leak

Ya i got the light during diagnosis. Pressure switch and lift pump leaking slightly, waiting for parts. If i feel for pulses on the actual six clear injector lines how often should they pulse?

Re: 2000 150hp ficht ram injection oil leak

Replaced the lift pump and pressure switch, purged the system. No more no oil alarm. Verified oil flow back to tank ok. Put pressure gauge on lift pump, all good 8psi. Used software to do static test of oil injector, all good. Thanks for all the help everyone its been a learning experience. Curious how many hours I can expect to get out of this motor?
